IPC: H05K9/00
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To absorb and attenuate high frequency component and to reduce the radiation of electromagnetic wave into atmosphere by sticking or coating an electromagnetic wave absorber on the whole inner peripheral surface of a control box. SOLUTION: This control box 1 of an inverter type resistance welding machine is constituted of a box body 2 with built-in electric devices, a box body 3 with built-in a timer and a cover body 4. The box bodies 2, 3 and the cover body 4 are formed with a steel plate 10, and filmy material consisting of the electromagnetic wave absorber 11 such as an elastomer mixed with ferrite is stuck over the whole surfaces of these inner surfaces. By this constitution, the electromagnetic wave of high frequency vibration produced from control devices in the control box 1 is absorbed and attenuated with the circumferential electromagnetic wave absorber 11 and reflected in the box bodies 2, 3 to prevent the radiation of the electromagnetic wave into atmosphere.  Further, propagation of the electromagnetic wave to an electric source, cable and transformer from the control box 1 is attenuated and the radiation of the electromagnetic wave is reduced.

Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To prevent influence to a memory cell which is not selected by providing wells which are formed between second separation areas and which are made of silicon into which impurity is implanted. SOLUTION: The plural second separation areas 46 which are isolated at constant intervals are formed on a first separation area 42, and one well 44, namely, an active area is limited with the two second separation areas 46. Conductive impurity which is similar to a semiconductor substrate 40 is implanted in the well 44.

Abstract: PURPOSE:To prevent a photosensitive drum from being damaged, to increase a corona discharge amount and to improve transfer efficiency by providing an endless film which comes into contact with the photosensitive body to form a toner image and a peeling and transferring means which peels and transfers the toner image on the endless film on a recording paper. CONSTITUTION:The surface of the photosensitive drum 1 is electrified with uniform charge by an electrified 2, and an electrostatic latent image is formed on the drum 1 by an exposing part 3. When the drum 1 is rotated and the electrostatic latent image reaches where a developing device 4 is positioned, toner supplied from the developing device 4 is attracted to the part of the latent image. However, since the endless film 5 exists between the developing device 4 and the drum 1, the toner which is to be attracted to the drum 1 forms the image on the film 5 and the toner image is transferred on the recording paper 8 by corona discharge in a transferring and peeling device 7. Therefore, the corona discharge at the time of transferring is increased without considering influence on the life of the photosensitive body, and the transfer efficiency is improved.
